APPARATUS FOR PU'RIFYING GAS.

Patented Sept. 7,1909.

Application filed January 15, 1909. Serial No. 472,517. v

To all QD/tOF/L if may concern:

Be it known that I, WILLIAM. lviorin'riiiin, a citizen of the United States, residing at Tenino, in the county of Thurston and State of lVashington, have invented a new and useful Apparatus for Purifying Gas, of

which the following is a specification.

This invention has reference to improvements in appt'iratus for manufacturing from l gnite and relates more particularly to the means for purifyingand storing the gas.

The object of the present invention is to provide a simple and etlicient means for purifying the gas produceddroin liqnite so that it may be immediately ready for use for illumination or heating.

The invention will be best understood from a'consideration of the following detail description taken in connection with the accompanying drawing, specification, in which drawing there is shown a vertical section of a gas holder and the purifying means used in connection therewith.

Referring to the drawing, there is shownv a holder 18 which may be of the ordi nary water sealed type and need not in itself be particularly described. The gas holder is mounted upon foundation walls i and the bottom 20 of thegas holder is provided with a passage 2t communicating with a. chamber 22 formed in a casing 23 housed within the foundation walls it) below the l)()li()lli 20 of the gas holder. The chamber 22 is in the upper end of the casing 23 while another chamber 24 is formed in the lower part of the casing 23, the two chambers be. ing se 'iarated by a perforated plate Ac cess to the chamber is had through a manhole 2i; and to the chamber 2% through a mauhole2i. Thepipe17entersthecasing23 and is then bcut upward into a loop 28 having the crown near the bottom face of the partition or plate 25 while the end of the loop 28 remote from the pipe 17 is bent downward as shown at 29 and terminates in an upturned end 30 opening near the bottom of the chamber 24. Another pipe 31 forming a part of this enters the chamber 24 and this pipe is provided with a tee connection closed-0n one side by a cap 32 and on the other side by a valve The chamber 24 is provided with a drain valve 34 near its lower end.v Gas within the gas holder 18 enters a pipe 35 and is conveyed thereby to any suitable, point of utilization. A

Within the chamber 24 there is a quantity of lime indicated at 36 moistened with Water until about the consistency of cream. Upon the plate or partition 25 there is produced a layer of coke and upon this a layer of sawdust and finally a layer of lime the en tire mass being indicated at 37. These several layers are introduced into the chamber through the manhole 26 while the liquid mass 36 of lime is introduced into the chamber 24 through the pipe 31, the cap 32 being removed for this purpose.

It is to be understood that the.apparatus described is designed more particularly for use in the production of heating and illuminating gas from lignite and more especizally the lignite found in the northwestern "sec tion of the United States. v

The gases coming from a suitable producer p: 's by the pipe 17 to the outlet 30. The F pass up through the liquid lime mass 36 into the chamber 24 and then through the perforated plate 25 and through the layers of coke, sawdust and lime into the chamber 22 and ultimately find their Way through the opening 21 into the interior of the gas holder 18 where the purifiedgases are stored until they pass by the pipe 35 to the point of utilization.

What is claimed is An apparatus for purifying gas containing lime iii a semi-liquid state and beyond the same in the path of the gas having a support containing co ke,- sawdust, and lime.

in testimony that'I claim the foregoing as my own, I have hereto aflixcd my signature in the presence of two witnesses. l LLIAM Mon {TH UR. li itnesses:
